TO AZLL WHOM IT MAY CONCERN:

Be it known that I, DAVIJD T. HUBBEL'L, of' the'tnwn of Bethel, in Vthe count-y of Fairfield, and Stam-of' Connecticut, have invented :in improved Method of SuspcnilingLanips; and I llo'hereby declare that the following is a full and exact description thereof, reference being hail to the accompanying drawings, and .to the letters of -rei'erence marked thereon. l

Figure I is a perspective view; and v Figure 2 is a vertical section, showing?r the operation. of" the workin-g parts. A is the pendantor case, in which the working parts-are placed, and is fastened to the ceiling of the rooin h3; the screws a a. B, 2, is the drum-wheeh'on whichV the suspending cha-in C is wound, ny the action of the spring D. E is a corrugated roller, over which the chain C works as the `lamp F is raised or lowered, and causing the lamp-F aml chain C always to .hang from the centr-e of the pendant A when at rest. The claws or pointsA H are .so placed that wheneverthe chain C falls 'to its natural or pcrpemliclar position, they catch and hohl the chain C :unl lmnp F at that point, the clawsfH being been: so as to be certain in their action, and prevent farther movement of the chair. up or down, accidentally or prematurely. I is a slot in the pendant A, which permits the chainto swing,` out one lside as :tt-K,-v thus releasing the chain C from the claws H, and permitting the lamp F to he adjusted to any desired position through the action of the spring D; and when so adjusted and brought back to its perpendicular position, it is again securely fastcnerl by the action of thelclaws H. ,is the frame in which the several Vpal-'lts work, made to facilitate the manufacture ami adaptation of its Several parts, and so asvto fit the insiflevof the pendant A, :Ludivine-n made tocomplete the whole by setting it into the VpendantV A, when it is ready for application and use. M is a rml, to which vthe stationary etnl of' the'spring l) is fastened.

My invention consists in having `the drum B so 4made andV arranged in ycombination withl `tlie`i`-ollierf1lthat whenever the suspending chain G fallsto the perpendicular, it will always han; from the centre ol' the pendant A, thus obtaining arid preserving -that; harmony of appearance which is always desirable, and ln'hicll is v,not secured with the conical drum arrangement'. in 'Harrison Weefls patent lanip adjuster, No.. 59,689, 18156, and the motion siileway's of the chain in it.' It furthei'consists in 'the combined action of'V the roller E anal the claws- H, B'y which the chain C is c: ught with certainty, when the-chain falls to the. perpendicular position, thus prevent ing the langer of breaking the lamp in being suddenly drawn up by the action of the spring D; also, in having all the working partsffitt'ed properly into the frame N, which is' made to fit the inside'oflthe pendant A, so as to secure prompt and positive action otv all the scvcraljparts; and in hose several parts -I ela-ini it as an. improvement on Harrison lVceds patent lai-ipp adjuster, No.'59,6$9, issuethin 186?. L i

l. I claim the arrangement and cornhi'nationof the mechanism consisting .of the drum B, spring D, roller E fclaw's H, ainill chain C, with frame N, as and for the purpose se-tforth. n* v .Z. 'I claim the pendant A, with its central opening anil slot I, in 'coxnhination with the above operating mechal'iisnnpas and for the purpose set forth,
